A BRANCH OF BIOLOGY THAT STUDIES THE INHERITANCE OF
TRAITS THROUGHOUT FAMILIES.
GENETICS
INHERITED FROM PARENTS, THE COMPLETE SET OF CODED GENETIC
INSTRUCTIONS(DEOXYRIBONUCLEIC
ACID)
D.N.A
THE UNSEEN GENES BEHIND A GIVEN TRAIT.
GENOTYPE
A GENETIC TRAIT YOU CAN OBSERVE.
PHENOTYPE
THE TYPICAL APPEARANCE OF AN
INDIVIDUAL IN A NATURAL POPULATION.
WILD TYPE
An individual of a species that lacks pigment cells and
appears pinkish white.
ALBINO
THE FATHER OF THE SCIENCE OF GENETICS.
GREGORMENDEL
A CHART THAT SHOWS ALL OF THE GENETIC
COMBINATIONS POSSIBLE IN THE OFFSPRING OF A
CROSS.
PUNNETT SQUARE
How scientists go about solving scientific problems.
PROBLEMHYPOTHESISEXPERIMENT
RECORD DATACONCLUSION
SCIENTIFIC
METHOD
(danio rerio) •Native to the Ganges River in India.•Tropical freshwater fish-needs warm water.•Easily and cheaply studied in the lab•Shares many characteristics with people
ZEBRAFISH
A trait that ONLY appears when NO
dominant genes are present (ex. blue eyes
and blonde hair in humans).
RECESSIVE TRAIT
A trait that appears MOST often in a
species (ex. brown eyes and brown hair in
humans).
DOMINANT TRAIT
A young organism before it emerges from
the egg.
EMBRYO
The part of the egg from which the
developing embryo gets nutrition.
YOLK
The entire genetic makeup of an
organism.
GENOME
A small dish that in which small organisms
can develop in a laboratory setting.
PETRI DISH
THE MATERIAL IN THE CELL NUCLEUS THAT
CONTAINS THE GENES (HUMANS HAVE 23
PAIRS).
CHROMOSOME
CELLS THAT CAN DEVELOP INTO MANY
OTHER TYPES OF CELLS AS THE EMBRYO
DEVELOPS.
STEM CELLS
